Gardaí are expected to charge a second person for the murder of Shane Geoghegan in Limerick almost four years ago.
The Garryowen rugby player was shot in a case of mistaken identity near his home in November 2008.
It is expected that a 29-year-old Limerick man will appear in court tomorrow morning charged with the murder.
One man has already been convicted of murdering Mr Geoghegan.
Barry Doyle, 26, from Portland Row, Dublin, was jailed for life in February after a jury found he had shot Mr Geoghegan in the head as he walked home in the early hours of 9 November 2008.
After the conviction and sentence of Doyle in February, gardaí said the investigation into the death of Mr Geoghegan would continue.
It is understood that following that investigation, the DPP directed earlier this week that a second man could be charged.
